lio it known that l, (nonun iliufrniiuq a citizen ol the ilnitcdtitulos-i, residing; at lnyton, in thc county of Montgomery and f'titatoot (lhiow hare invented certain new and useful Improvements in ftlhccls7of which the following is n specification, reierence being had thereinto the accompanying drawing.

My invention relates to casting and in particular tocast steel wheels.

llt is the object of miy invention to eliminnie the use of the copeportion of the flask and the green sand therein together With thenecessary moulding of the sand, and the handling of the 'linsltcontaining it.

It is the object of my invention to provide mechanism to take Athe placeoi thecope Which Will permit of rapid nnd economical mnnut'acture ofcast wheels and similar manufacture of the parts substituted for thecopo.

This part consists of a dry sand copo core member which may loc readilyand easily handled without the necessity' of a crono or similarapparatus;

.it is my object to provide asingle member of this character with apouring gate inv place of the cope thus lgreatly shortening the timenecessary for the assembling of the flask, green sand and cores.

Referring tothe drawings: i

Fig. lis a section through the assembled apparatus;

Fig. 2 is a section taken on the line 2-2 ofFigl; i

Fig. 3 is a' plan View taken on the line 3-3 of Fig. l.

'Referring to the drawings in detail, 1 is e bottomboard, and 2 the dragportion of 'the flask mounted thereon.

` `Within the drag portionis the customary green sand 3. The hub core 4is located upon the green sand centrally adjacent the drag' portion 5oit' the cores Jfor the spokes and rim.

6 is thecope portion of the cores `for the spokes and rim. 8 is` thcspoke portion. 9 is the rim portion and '10 is the hub portion ot thecopecap-'corc which has an arbor 10 moulded therein with projectingradiating `members.11resting Vupon the top of the flask 2. These membersare. positioned on the ask by the pins 12. They are further iostionedand clamped-by the clampsl ll. Serial No. 572,833.

which engage at three points as bearing,` points, the nicnilicrs ll andthe ilangc l--lel' the' flask. ln order to lock; those puits iuengagement wedges l5 arc proridcd.

A. pourinw cup i6 is provided ol: dry sand and is held in place by apouringl cup ring 17.

rJhe metal is poured in the openinga lil and fills the space around thehub core und the spoke and rimcorcs to form the wheel.

lt Will be apparent as the spoke and -rim cores and hub core are placedinto position all that it is necessary to do to complete the mechanismfor pouring` is to put the single cap structure into place positioningit by the pins l2 and clamping it by 13 and l5 Where, upon thcl lockingoiE 1G and l? the Wheel cnn be poured.

lt will bc understood that l do not desire to be confined to thisspecific adaptation ot niy invention but comprehend within it suitablemoditications which may bc neces sary to ada'it it to varyingrconditions.

Having tius fully dcscribcd my invcntion, Whnt l claim as new und desireto secure by Letters latcnt, is:- I

l. ln combination a flask consisting.;n ot a drag portion, a bottomboard. gri-cen' sund therein, hub, spoke and rim cores. cope cap coro,meansv in said last mentioned coro for locating it withrespcct to thetlask. means Of clamping said locking means to the flask and n pouringcap core and means to maintain last mentioned core in position.

, 2. ln combination a. drag portion of a. Hask having green sandtherein, a bottom board, hub., spoke and rim cores located in tho fiasksaid cores having;a cope and drag portions, a cope cap core havingarboretherein and a plurality of projections therefrom, means on some of saidprojections for positioning the cope cap core. and means on some of saidprojections for locking said cope cap core tothe flask.`

3. In combination a. drag` portion of a flask having green snnd therein.a bottom bonrd,hub, spoke andfrim cores located in thc flask said coreshaving cope and drug portions. a Cope cap coro having' arbors thereinand a plurality of project ions there from, means on somo yol" saidl'irojoctions for positioning the cope cnp coro., means on some of saidprojections 'tor locking saidv cope cap core to thc flask, and a pouringcap-core.

fi. In combination zi drag portion of :i Ilzisk having green sandtherein7 ai boztoxn bom-d, hub, .Spoke incl fini cores located in theflask said Cores having" cope and drag portions, a Cope Cep core havingarbore lieiein end 'e plurality of projections there l iom, means onsome of seid projections v for positioning the cope cap core, means onLeve-eee :ind the locking means being located at three points equaldletances from one another.

In teslmony whereof, I ax my signature.
